condensers and the object of the invention is to provideA such. a device embodying various novel features designed for the purpose of securing increased economy and efficiency. l

The invention includes the special features of 'construction and arrangement and combination of parts valve indicated at 32 which is opened when the conplate 4 arranged directly beneath the central opening hereinafter described and particularly set forth4 in the l appended claims.

A condenser embodying my 'improvements is shown Figure l is a sectional elevation. F ig. 2a sectional plan. Fig. 3 a section on line A-A of Fig. l, and Fig. 4asectional detail. y i

Referring lto'reference characters to. this drawing, the numeral l designatesthe exhaust pipe leading from the engine Whose steam is toV be condensed. This has i one branch communicating with the condenser body 2 and another branch 33 forming a free exhaust pipe which is provided with Vany suitable for/m of automatic denser is'disconnected from the exhaust. The condenser body 2 may conveniently be made with. its main portion of cylindJical form and with tapered or contracted bottom and top as indicated at 5 and 7 The ex haust pipe l communicates by Iits lateral branch'lu with an. annular chamber 35 completely encircling the condenser body or drum andV communicating with the in- -terior thereof by a. 4 plurality of verticallyi elongated apertures 35 as shown. At the right hand side of the cham- -ber 35 is shown a small section of pipe 1l which is to indicate that when desired the exhaust of more than one 4engine may be connected Witha single condenser. At

its lovver end the condenser body or drum communicates by a pipe e 4with the het wen 23.

At l2 is shown 'a storage regulating and separating tank for Waterand air, from the 4side of which, near the lower end leads -a pipe 8ior supplying spray Water to the condenser.. This spray water strikes upon a centrally arranged deflecting orv baffle' plate 34, preferably provided vvith an annular flange 34, vand fallingover the edge of this strikes upon a second annular badje plate 3 located just above the elongated steam inlet openings through which the steam enters in radially converging jets. Below these openings is a third central baffle of the plate 3. 'Within tlie valve chamber 9 of the pipe 8 is "a valve l0 having an'A operating lever'll del signed to be operated in connection With the steam throttle in thc mamier described inliet'tel's Patent of the United States granted to me on the 5th day` of December 1905 and numbered 806,368. The tank l2 is supplied with Water from asupply pipo leading from any suitable source of supply, as for instance the ordinary feed water pump, not shown) the pipe leading into the bottom oi' the tank and being provided with an air separating nozzle as shown. I

At 18 is shown a pipe which has one branch l5 connected with the top of the storage tank and another pipe l7 connected with the top of the condenser body 7 its end 22 depending Within an air separating chamber 19. This chamber is connected to the upper part of the storage'tank l2 by a connection 14 and has an overlow or return pipe 2l leading from its lower end to the hot Well.' Its upper end is connected by a pipe 2() to the ordinary dry vacuum pump (not .hown). The exhaust pipe l is provided Wi i1 anozzle 25 for a drain valve 26 under pressure of a spring 27. The valve s'tem 28 is provided with u elongated slot 29 which is engaged by one end' of a lever 30 conne 'ad to a rod or the like 3l leading to the engine pui` 't w... acby the engineer may operate the drain valve positively, said valve 'operating automatically when the end. of the lever is in neutral position or midway of the ends ofthe slot. i

Having thus described the construction and arrange ment of parts of my condenser I will brieiiy set forth the functions of the variousparts and the advantages thereof.

The annular inlet channel by which the exhaust steam is discharged into condenser' concentrically and is brought in Contact with the spray from the lower spray plate, in form of a uniform steam spray, avoids a one sided steam current, which requires more spray VWater and -fnore vacuum'pump capacity.

By the arrangement and shape of the spray plates, the upper one reverses the flow of Water forming thus a paraboloid by the down coming Water, which the up coming steam and air have to penetrateradially fromI inside to outside. The intermediate spray plate on which the Water falls causes the Water to spray on the up-coming 'steam ony the inside and on the outside on the inside of the condenser body; while the water comingdown from the intermediate spray plate in the shape of the inner part of a paraboloid of annular horizontal section through which the steam is forced to pass concentric froin the outside toward the center, the exhaust steam being at the same time subject to the action of the spray effect, caused `by the lower spray plate. It is this spray-like injection ofthe steam and the zigzag way it is forced to take, by the arrangement 'and form of spray plates, which guarantees a thorough mixture of the exhaust steam and spray Water, requir ing thus the least amount of spray Water, While at the same time the highest possible vacuum attain ed.

' f Tl'ie'storage tankl2 furnishes a maximum quantity o Water at the disposal of the engineer, which is always replaced While the engine runs on light loads, b v means ot valve 9 which is intended to b e operated automatically whenever the throttle -valve lever is operated, as in my patent. above referred to. This is particularly intended lor reversing engines and enginesn'orking with a great change in power and ste-ain consumption. It also gives a constant head oi' resistance to the-pump furnishing the cold water for condensing the exhaust steam. This constant head is the agent for acting upon the pump motor regulating device. lt may be a. steam turbine pump, electric motor or steam engine driven pump. It also enables me to separate the cold air lrom the water uscdf-lor eondcnsinpr the steam. before the water ente the condenser7 drawing thus the air oil before it is heated in the condenser, which would require a larger vacuum pump. Nozzle 13 with slots is int-ended to help to force tbe air away from the opening,vr leading into condenser and bring it all to the top where it is drawn oft. through nozxle l5 which is in connection with the dry vacuum pump. lt. also serres to conduct all condensation matter coming from vacuum' suction line throughthe tank overllow into hot Well.

The automatic drain and positively operated valve will open automatically if engine and vacuum pump7 or the pump furnishing the water lor condensing the. exhaust steam is stopped, or it' the engines and all pumps are stopped7 that. the condensing plant. l3nt there is always a certain amount ol steam leaking through the engine throttle valve, which will iin'ally cond ense in the exhaust pipe. Also vapor in the condenser and vapor coming from hot well will precipitate in exhaust pipe and it theI engines are idle, for any length of time, the horizontal part of exhaust pipe'will partly, or may lill completely, with such condensation water, which, it' the engine is started up again, is drawn into cyl in ders and since it cannot escape all through'exhaust port during the return stroke on account of overlap oi engine valve, it will either break the. engine piston orA cylinder head and may break up the engine complete. The application ot' the automatic valve makes this impossible, as the valve will open directly after the Vaeu um is broken through one or the other pump breaking down or when the engines and condenser' are set still.

This ralre is also intended to be operated by the engineer from the pulpit for blowing out the exhaust pipe and lor reasons of inspection.

Having thus described myfinvention. what l claim isz tant annulnrly arrnngedv'inlet openings for the exhaust steam. :i water supply; pipe at the upper end of said body. a centralb arranged baille plate beneath said pipe. and above said openings. and a baille plate-below said inlet opening-s.

2. ln combination, a condenser body having' annularly.

arranged inlet openings for tbe exhaust steam. a water Ivapply pipe at the upper end of said body. a centrally :irrang'ed batlle plate beneath said pipe. an annularly arranged baille plate beneath saidvtirst named plate and above the steam inlet openings and a third and centrally i --"me-ed baille plate below said opening-s.

3. lhe combination with a condenser haring means for .admitting exhaust steam thereto, of an elevated water storage tank, means for feeding.- water from said storage tank and spraying it upon the steam in the condenser and an overflow pipe to maintain a constant head for regulatine,l the water pressure in the feed pipe and the speed ot' the pump, motor or engine.

L In combination, a condenser' body for receiving exhaust steam, a storage tank elevated above the level of the condenser body and having a connection for supplying* spray water to said vcondenser body. a valve in said connection for controlling; the passage of the water from the tank to the condenser body. and a water supply to said storage tank. and a vacuum pipe in connnunication with the upper portion of said condenser bod)- and storage tank.
